Description

Spring disk type fiber yield scale

The utility model relates to a kind of spring disk type fiber yield scale, belongs to measurement instrument.

According to preliminary search, there is not to find identical therewith fiber yield scale.Lint percentage is the important indicator that cotton is worth, and because of there not being special-purpose measurement instrument, therefore can only substitute with counter scale for a long time.With the counter scale weighing unginned cotton respectively sample and the quality of rolling back gined cotton, by calculating lint percentage, the mensuration process is comparatively complicated again, and the slow and accuracy of speed is difficult to control.The lever fiber yield scale of Indian cotton flower processing technique research institute design, though can directly obtain the lint percentage reading on the indication disk, accuracy is also higher, but reach 0.25%, but because the lever balance time is longer, (about 20 seconds) measuring speed is slower.A kind of electronic scales of being furnished with micro computer of Chu Xianing can directly demonstrate lint percentage by the quality of weighing unginned cotton and gined cotton in recent years, characteristics such as speed is fast, precision height that it has, but cost an arm and a leg, purchasing test unit of general basic unit is unable to reach.

The purpose of this utility model provides a kind of fiber yield scale of spring disk type, and it has characteristics such as measuring speed is fast, accuracy is high, with low cost, easy to use concurrently, to overcome the deficiency of prior art.

The skin scale that the utility model is related, by the sample tube, carriage, bearing frame, spring, the rack pinion assembly, index dial, pointer and support are formed, it is characterized in that bearing frame (center line is perpendicular to the support bottom surface) all adopts hinging manner to be connected with travel(l)ing rest (two isometric parallel metal bars) and travel(l)ing rest with a side of support, " L " shape tooth bar (parallel with the bearing frame center line) that is positioned at the bearing frame opposite side and is connected as a single entity with it is meshed with the gear (its central axis and support lateral vertical) on being fixed on support, form rack and-pinion mechanism, the spring that the root of " L " shape tooth bar and support cap base are provided with vertical hanging, the index dial that is carved with unginned cotton heavy surely (full scale) and lint percentage (1000 or 500 little lattice of five equilibrium of the radian between zero-bit and the full scale) is fixed on the close support of rack and-pinion mechanism one side, its center of circle overlaps with the gear centre axis, and pointer is installed in the gear shaft top of stretching out the index dial center pit.

The utility model compared with prior art has characteristics such as simple in structure, easy to use, with low cost, that detection speed is fast, especially is fit to Cotton Inspection department of basic unit and uses.

Fig. 1 is a front elevation of the present utility model.

Fig. 2 is a side sectional view of the present utility model.

Among the figure, [1] is that sample tube, [2] are that lower limit screw, [7] for spring, [8] for tooth bar, [9] for gear, [10] for index dial, [11] be pointer, [12] be support for travel(l)ing rest, [5] for upper limit screw, [6] for bearing frame, [4] for carriage, [3].

Below in conjunction with drawings and Examples the utility model is described:

With full scale is that 1 kilogram skin scale is an example, sample tube [1] is a cylindrical container, can adopt metal or plastics to make, carriage [2] and bearing frame [3] hardware for fusing, both geometric centers are positioned at same axis (perpendicular to support [12] bottom surface), travel(l)ing rest [4] is by two isometric metal, rod-shaped compositions, one end and bearing frame [3] are hinged, one side of the other end and support [12] is hinged, both keeping parallelisms, bearing frame [3] go up with travel(l)ing rest [4] a symmetrical side one " L " shape metal rack [8] (parallel with bearing frame [3]) and two stop screws [5] are arranged, [6], upper limit screw [5] places the top of bearing frame, lower limit screw [6] places the root of " L " shape metal rack [8], its effect is the displacement range that the control bearing frame moves up and down, be connected with the spring of a vertical hanging between " L " shape metal rack [8] and support [12] top cover, spring with the steel wire of 1MM close around, external diameter is 18MM.Gear [9] is fixed in the sidewall of support [12], be meshed with tooth bar [8], the effect of this rack and-pinion mechanism is that the displacement of the lines with bearing frame [3] converts angular displacement to, both moduluses are M=1, the tooth number Z of gear=16, the axle of gear [9] is vertical with the sidewall of support [12], be carved with the heavy surely and lint percentage scale of unginned cotton on the circular scale [10], the full scale (1 kilogram) of index dial [10] is heavy surely as unginned cotton, (is zero-bit that sample tube [1] is when unloaded, pointer [11] position) is divided into 1000 lattice to the radian between the full scale, then each lattice is represented lint percentage 0.1%, index dial [10] is fixed on the outside of support [12] sidewall, its center of circle overlaps with the axle center of gear [9], and the central shaft of gear [9] passes index dial [10] center pit, and pointer [11] is equipped with on the top, therefore the deflection angle of pointer [11] is corresponding one by one with the displacement of bearing frame [3], and is linear relationship.

Principle of work of the present utility model is as follows:

When sample tube [1] is unloaded, spring [7] is stressed less, bearing frame [3] is approaching at upper limit position, the pointer indication is in zero-bit, when sample tube [1] adds the cotton load, the stressed increase of spring [7], bearing frame [3] moves down, its displacement is heavy linear with load, so the deflection angle of pointer [1] is also linear with load.Put into the unginned cotton sample during use earlier and focus on the full scale place surely, examination shuts out gined cotton again during weighing, and the indicating value of pointer [1] on index dial [10] is the lint percentage of cotton.
